Newly single Russell Simmons arrived at the Cinema Society’s premiere of “Friends With Kids” Monday night with Angela Martini — the stunning former Miss Universe contender and swimwear designer — on his arm. But Martini, who made head-lines last year when she dated another model-chasing hip-hop mogul, Kanye West, seemed to go out of her way to express the two were just “good friends.” “With my good friend @UncleRUSH chillin having great time w/him and other friends,” she tweeted from the Top of the Standard after-party. The Albanian’s the latest in a string of beauties spotted with Simmons since Page Six revealed last month he’d split with actress Melissa George. Other couples enjoying the evening included Cheryl Hines and Robert Kennedy Jr., Ed Burns and Christy Turlington and Megan Fox and Brian Austin Green. The film’s pairing of “Bridesmaids” stars Jon Hamm and Kristen Wiig (above) brought out a raft of comedic actors including Paul Rudd, Jonah Hill, Seth Meyers, Fred Armisen and Sarah Silverman. When writer-director Jennifer Westfeldt, who’s also Hamm’s longtime partner, introduced the film at the SVA Theatre, she went through a long list of names, and when she came to the “Mad Men” stars, Hamm shot to his feet saying, “Thank you, thank you, thank you,” which drew huge laughs.
